pain/dull ache, stiff, TTP

20
Q

What is the primary treatment focus for Bursitis?

A

pain and inflammation

21
Q

How do you restore normal patellar motion?

A

VMO strengthening
Stretch Lateral Structures
Align Foot/Ankle/Knee/Hip
Hip ABD strengthening

22
Q

What are the common areas affected by tendonitis in the lower extremity?

A

Patellar Tendon
Quad Tendon
Pes Anserine

23
Q

Quadriceps and Patellar Tendonitis usually result from what movement

A

Excessive load in jumping

24
Q

Pes Anserine tendonitis is a result from what movement?

A

Low-load repetitions like running, swimming, biking

25
What muscles are stretched for pes anserine tendonitis?
Sartorius Hamstrings Gracilis
26
What muscles do you strengthen for pes anserine tendonitis?
Quads Hip Abd Glute Max Ankle Invertors to improve knee alignment **Decrease medial knee stress with valgus movement
27
What is Patellofemoral Pain syndrome (PFPS)
pain in and around the patella as a result of increased or abnormal mechanical forces between the patella and femur
28
What activities increase patellar stress?
Jump Squat Kneeling Prolonged sitting with knee flexed Stair Climbing
29
What factors affect Patellofemoral Pain Syndrom
Tight lateral retinaculum Tight IT band Increased q Angle Weak Vastus Medialis (VMO) Stretched Medical Retinaculum or medial Patellofemoral ligament
30
Tight hamstrings make quads passively insufficient so they require what?
increased quad contraction
31
What is chondromalacia
softening of articular cartilage in a GRADE 1 (aka runners knee)
32
What is exposed in a GRADE 4
full-thickness with exposure of subchondral bone
33
How do you restore or improve patellar tracking/patella compression?
Stretch tight lateral structures Strengthen VMO Control of Q Angle and Knee position
34
How do you control q angle and knee position?
Minimize: foot pronation Medial Tibial/Femoral Rotation Hipp Adduction
35
Surgical: Lateral Release
release of lateral retinaculum may include shortening medial fibers
36
Surgical: Patellar Realignment
cutting and moving of tibial tubercle to change the angle of pull
